Increasing the depth of manure injection or incorporation from 5 to 10 cm can be considered for further abatement of NH3 (g) and N2O (g) emissions, since deeper burial of manure increases the diffusion path to the soil surface of these reactive N gases while promoting the biological reduction...
(Pushpadass et al., 2010). Polystyrene-graft-starchcopolymersare extensively used in various sectors, such as food packaging, textile industry, and water pollution treatment. The burial method has been developed to degrade modified polystyrene biomaterials by using different soil types, e.g. humus...
Liquids such as condensate, butane, and propane may be recovered at the gas plant and allocated to individual wells based on their gas analysis and flow rate. Oil is metered, for example, with a positive displacement meter and either pumped to storage tanks or a transmission pipeline. If the...
supplied from astorage tank, was introduced to each autoclave compartment. Liquid oxygen was delivered by truck to a storage tank from a nearby oxygen plant. The oxygen was vaporized and introduced to each compartment. Exiting slurry passed through three stages of pressure...

and finally stabilizes as lead-206. Radon-decay elements occur as a shiny film on the inner surface of the inlet lines, treating units, pumps, and valves associated with the processing systems forpropylene, ethane, and propane. The NORM waste may occur in a crystalline form, in carbonate mat...

Internal combustion (IC) engines for motor vehicles are of two kinds:spark ignition(SI) andcompression ignition(diesel). The SI engines use gasoline, alcohol, or compressed natural gas fluids (propane) or compressed natural gas as fuel; introduce the fuel to the cylinder by carburation or injec...
